Well, I somehow got a notification from the app that I had two drivers needing updating. A window appeared on the lower right of the screen. So some part of it succeeded I believe. And I find the program on my program list, with an option to uninstall which Windows cant do (can't find it).
I think I will try deleting it from the chest, and removing it from my program list, and hope there isn't some kernel of it still working.
